    Patent number: 4137454
    Abstract: In pulsed X-ray fluoroscopy in which the fluoroscopic screen receiving the X-rays is subsequently observed by a video recording system incorporating an image intensifier, the quality of the video image is impaired because of electrical noise and phosphor flare. The image quality is improved by reducing the gain of the video system synchronously with the occurrence of each X-ray pulse. In addition, the residual disturbance left on the video output is stabilized by synchronizing the video framing cycle frequency with the X-ray pulse frequency.
